This is the most challenging work that I have ever done in awhile to use zbrush to create an environment. I'm still new to make the environment arts and I know I still have a long way to learn more. If you need any suggestions that I should work on more for next environment, PLEASE let me know and I will appreciate that a lot :D
Soon I'm going to learn how to use Unreal Engine which I'm very exciting to learn to make more environment artworks :)
